[fix]: images loads too slow

since we are storing our images in heroku server the image loads too slow in our fronten which results in shifting of layout after user has opened the loadin, create account page.

Plan : store img in cloundary, use some packages to load that image fast something like gatsby image would help.

Start by tracing how images are stored and loaded on the loading and create-account frontend pages, then measure the current loading behavior and layout shift. Compare the existing approach with the issue's Cloudinary and Gatsby Image suggestions; done means the affected images load faster without shifting the layout.
